I found this today on my HD it was some gps soft. Im not exactly sure what it does cause I havn't gotten a change to look though it. *I did not write this* I had this from back in the day when i had a computer in my car for a mp3 player. I think this is the software i was messing around with to tell direction, etc...
Hope this helps. I can't test it cause I can't find my gps and im in the process of looking for a new one.
